  • You have worked with at least one columnar database (Druid, ClickHouse, Snowflake, Vertica, …) and know how to analyze and optimize queries for it

  • You have worked on a large go application with a considerable amount of traffic (>100e6 requests per day)
  • You are open to relocating to Hamburg, Germany
  • Plus: You have experience working with infrastructure as code (Terraform), Docker, and serverless infrastructure
